ScreenCastle is an online screencast recorder. This is a simple tool to use if you want to capture the how to steps of any online program you might want to demonstrate for students. Just launch the red record button in ScreenCastle to record. When you stop it, your screencast turns into an embeddable video. Neat! Another previously posted screencasting tool that is just as easy to use for this purpose is Screencast-O-Matic.
